Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

Example 1

2 to 4 show the structure of the three-dimensional signboard according to the present embodiment.

As shown, the three-dimensional sign according to the present embodiment, the bottom mounting portion 100, the light emitting unit 400 is installed, and the middle receiving portion 200 is formed along the bottom mounting portion 100, the through-hole is formed And, it is composed of a light transmission cover 300 is installed on the upper portion of the intermediate receiving portion (200). As the light emitter 400, a light emitting diode may be used. Of course, in some cases, the light transmission cover 300 may be excluded to expose a lamp such as a light emitting diode.

First, the mid-receptor 200 has a configuration in which any one of epoxy, acrylic, UP, and resin is infiltrated and hardened into a medium density fiberboard (MDF) material. MDF itself has a small stiffness and a very weak property to moisture, but when the material of any one of the epoxy, acrylic, UP and resin is immersed and cured, it is very rigid and excellent in water resistance.

In addition, the light transmission cover 300 is bonded at the upper end of the middle receiving portion 200, it is a plate-like component made of any one of the light diffusion material of epoxy, acrylic, PC (polycarbonate) and synthetic resin plate . Bonding of the light transmissive cover 300 to the intermediate receiving portion 200 may be made of any one of a liquid epoxy, acrylic, resin, and trims around the symbol or letter (sometimes called '쫄') Joining is possible by work. Moreover, conventional adhesives (aka bonds, instant adhesives, etc.) may also be used.

On the other hand, as shown, the floor mounting portion 100 is integrally formed of the same material as the middle receiving portion 200.

However, it is of course possible that the bottom mounting portion 100 and the middle accommodation portion 200 are bonded to each other. This is possible due to the property that MDF is very strongly adhered by piece (screw) or liquid epoxy, acrylic, UP or resin (adhesive) or general adhesive.

Hereinafter, the manufacturing method of the three-dimensional signboard according to the present embodiment will be described.

First, the MDF is automatically cut according to shape data and a program to process a predetermined shape and a light emitting accommodating groove 250 so that the bottom mounting portion 100 and the intermediate accommodating portion 200 are integrally formed. Automatic cutting can use the automatic cutting device using computer such as NC, CNC engraver, equipment, etc.

Here, the outer shape means an outer shape such as a predetermined letter or symbol, and the light emitting member receiving groove is formed in the width of the letter or symbol and is a groove portion in which the light emitting body is installed. Therefore, the external shape and the light receiving body groove can be smoothly cut by a rotary cutter made of tool steel or cemented carbide. Thereby, the structure in which the bottom mounting part 100 and the middle accommodation part 200 were formed integrally is obtained.

Next, the bottom mounting portion 100 and the intermediate accommodation portion 200 formed integrally soaked by curing any one of the liquid epoxy, acrylic, UP and resin. This is possible by vacuum-impregnating and removing the bottom mounting portion and the intermediate accommodating portion from the liquid for several tens of seconds or several minutes, and in some cases, it can be expected to have a stable waterproof effect if the work is repeated one or more times after curing. Instead, it is also possible to apply the liquid to the surfaces of the bottom mounting portion 100 and the intermediate accommodation portion 200 formed integrally.

Next, the light emitting unit 400 is installed in the bottom mounting unit 100 of the light receiving unit 250. To this end, the floor mounting portion 100 is provided with a place for the light emitting unit 400 is installed, the bottom mounting portion 100 or the middle receiving portion 200 is formed with a hole through which the power line passes.

Next, the light transmission cover 300 formed of any one of epoxy, acrylic, PC, and synthetic resin is bonded to the upper end of the intermediate accommodation part 200. In this case, a liquid epoxy, acrylic, resin, or a general adhesive may be used as the bonding agent, and may be attached by trimming.

Example 2

5 to 7 show the structure of the three-dimensional signboard according to the present embodiment.

In the present embodiment, the light transmission cover 300 made of any one of epoxy, acrylic, and synthetic resin is integrally formed with the middle receiving portion 200 made of MDF.

In addition, the floor installation unit 100 is MDF is made of a cured material of any one of epoxy, acrylic, and resin bonded to the middle receiving unit 200, the light emitting body (on the floor installation unit 100) 400) is installed.

The rest of the configuration is similar to that of the first embodiment.

Hereinafter, the manufacturing method of the three-dimensional partition board which concerns on a present Example is demonstrated.

First, the intermediate container 200 is formed by automatically cutting the MDF according to shape data and a program to process a predetermined shape and a light-emitting body accommodating hole.

The middle receiving part may have a double thickness depending on the depth of the three-dimensional signboard since the thickness of the commercially available MDF product is limited.

Moreover, if the width and depth of the three-dimensional signboard are widened, the first process is gradually thickening from the upper end to the lower end of the intermediate receptacle, and secondly, from the upper end to the lower end of the intermediate receptacle or at the bottom of the bottom mounting part. It is also possible to prevent the warpage and cracking by imparting additional stiffness by nailing Taka nails in the upper direction, and to further strengthen the product by laminating glass fibers in the middle receiving part or the bottom mounting part after impregnation hardening. .

On the other hand, another MDF is automatically cut to fit the outline of the predetermined letter or symbol to form the floor mounting portion 100.

Automatic cutting can use the automatic cutting device using computer such as NC, CNC engraver, equipment, etc.

Here, the outer shape means an outer shape of a predetermined letter or symbol, and the light emitting member receiving groove is formed in the width of the letter or symbol and is a groove portion in which the light emitting member 400 is installed. Therefore, the external shape and the light receiving body groove can be smoothly cut by a rotary cutter such as tool steel or cemented carbide material.

In addition, one of the liquid epoxy, acrylic, UP, and resin soaked into each of the bottom mounting portion 100 and the middle receiving portion 200 to cure. This is possible by vacuum-impregnating the bottom mounting portion and the intermediate receptacle in the liquid for several tens of seconds for several minutes. Instead, it is also possible to apply the liquid to the surfaces of the bottom mounting portion 100 and the intermediate container portion 200.

In addition, any one of the liquid epoxy, acryl, and synthetic resin is accommodated in the state in which the upper end of the middle accommodating part 200 is in close contact with the glass surface treated with a releasing agent (the upper end of the middle accommodating part is disposed downward). It enters into the space formed by the upper opening of the part 200 and the glass surface, and fully hardens to form the light transmission cover 300.

The light transmissive cover may be cured in the transparent state of any one of epoxy, acrylic, and synthetic resin and then attached to the surface of the light transmissive cover, but in some cases, a light diffusing agent may be added, or a pigment, dye, or ultraviolet ray may be used. It may be formed including additives such as stabilizers.

The impregnation depth of the upper portion of the intermediate receiving portion 200 will correspond to the thickness of the light transmission cover 300 is made. In this case, time is kept to cure sufficiently.

When curing is completed, the glass surface is separated from the upper end of the middle receiving portion 200 and the light transmission cover 300. By doing in this way, the structure by which the light transmission cover 300 was integrally formed in the upper end opening of the middle accommodation part 200 is obtained.

On the other hand, the floor mounting portion 100 is provided with a light emitting body 400, and the bottom mounting portion 100 is bonded to the bottom of the intermediate receiving portion 200. In this case, a liquid epoxy, acrylic, UP, resin or a general adhesive may be used as the bonding agent, and can be attached by piece fastening.

Other Example

As described in Example 2, instead of curing the upper end of the intermediate receptacle 200 in the state of impregnating any one of the liquid epoxy, acrylic, and synthetic resin to form the light transmission cover 300, simply the curing A light transmission cover 300 composed of any one of epoxy, acrylic PC, and synthetic resin board is bonded to a top of the processed intermediate receptacle 200 with a conventional adhesive, while the bottom of the light emitting unit 400 is installed in a hardened state. The attachment portion 100 may be joined to the bottom of the intermediate accommodation portion 200.

The above embodiments merely illustrate the most preferred examples of the present invention, and various changes or modifications may be made by those skilled in the art within the spirit and scope described in the appended claims.

According to the present invention having the above-described configuration, since the MDF which is excellent in cutting processability and low cost is simply automatically cut and manufactured by bonding or the like after hardening by applying or impregnating any one of epoxy, acrylic, UP and resin thereto. Very sophisticated and inexpensive three-dimensional signs can be provided.

In addition, by gradually increasing the thickness from the upper end of the middle receiving portion to the bottom direction, using a nail nail to prevent bending and cracking, and laminated glass fibers can be further enhanced the robustness and stability.

In addition, by simply impregnating the cured intermediate accommodating portion into any one of liquid epoxy, acrylic, and synthetic resin, the light transmitting cover can be integrated into the intermediate accommodating portion, thereby making the product smooth and excellent in appearance.

In addition, the MDF can be processed by automatic cutting using a computer, so that a precise product that meets the requirements of the consumer can be produced in a short time.

In addition, since epoxy, acrylic, UP, and resins are simply used as binders or only applied to some parts, the price is greatly reduced.
